The third condition (REF ), \(\Vert \mathcal {M}_\text{i}\Vert  \le \gamma \) , is proven in [1]} and holds with probability at least \(1-\text{N}^{-\alpha +1}\) , \(\gamma =\sqrt{2\text{N}(\log (2\text{L}_\text{i}\text{N})+1)+1}\) , \(\alpha \ge 1\) , and
\(\alpha \le \min _{\text{i}\in \lbrace 1,2,\dots ,\text{R}\rbrace } \left(\rho _{\mathbf {\Psi }_\text{i}}^{(\text{L}_\text{i})} \log (\text{N})\right)^{-1},\)
